In an embodiment, the bulk chamber 102 includesmethylated crystalline cellulose (MCC) as a formula delivery vehicle.

In an embodiment, other parts of the bottle 100, including the cap 104,spout 116, bulkhead 118, and cartridges 200, 300 can be made from theabove-mentioned materials.

In one embodiment, the cap 104 includes a levered spout 116 that pivotsto open and close a passageway for dispensing the liquids. For example,in the position illustrated in FIGS. 1 and 2, the levered spout 116 isdown closing the passageway, while in FIG. 3 the levered spout 116 is upopening the passageway and allowing dispensing of the liquid mixture. Inone embodiment, the levered spout 116 pivots between the open and closedposition by pivoting at a fulcrum, so that opening and closing thepassageway depends on depressing the levered spout 116 at one or theother side of the fulcrum.

Referring to FIG. 2, in one embodiment, a bulkhead 118 connects the bulkchamber 102 to the cap 104. The bulkhead 118 can be made from rigid orsemi-rigid plastic. In one embodiment, the bulkhead 118 can thread on tothe top end of the bulk chamber 102. In one embodiment, the bulk chamber102 has outer threads on the upper end of the chamber 102, and thebulkhead 118 can have matching inner threads on the lower side thatthread on to the lower chamber 102. Further, the bulkhead 118 can haveouter threads on the upper side that allow the cap 104 with innermatching threads to thread on to the upper side of the bulkhead 118.

In one embodiment, the bulkhead 118 also prevents the liquid in the bulkchamber 102 from mixing prematurely with the additive liquid 122. Thebulkhead 118 includes a flat disk 112 that seals the bulk chamber 102 ontop except for a small opening 110 to which a diptube 108 is attached.The diptube 108 extends down from the opening 110 to the bottom of thebulk chamber 102.

In one embodiment, the bulkhead 118 also includes a magazine 106. In oneembodiment, the magazine 106 is a cylindrical tube with an opening 114level with the disk 112, and the magazine 106 extends down into the bulkchamber 102, but is closed on the bottom. The magazine 106 is acompartment to hold the replaceable cartridges 200, 300 with theadditive liquid 122. The magazine 106 may have an inner diameter thatmatches with the outer diameter of the cartridges 200, 300 so as toprevent the cartridge 200, 300 from falling out when the containerbottle 100 is tipped upside down.

The cartridges 200, 300 hold the additive liquid 122 that is mixed withthe bulk liquid 120 upon dispensing the bulk liquid 120 so as to givethe dispensed bulk liquid a desired characteristic. Cartridges 200, 300are generally cylindrical closed-bottom vessels. The cartridges 200, 300are replaceable and interchangeable to give the consumer a variety ofchoices. The cartridges 200, 300 can be made from materials similar tothe bulk chamber 102.

In one embodiment, cartridges 200, 300 have dissolvable shells, and thedissolvable cartridges 200, 300 can be inserted in direct contact withthe bulk liquid 120 in the bulk chamber 102, which causes thedissolvable shells to dissolve, and dispensing the additive liquid 122into the bulk liquid 120. In one embodiment, a dissolvable shell is madefrom poly(vinyl alcohol) or its derivatives and copolymers. In thedissolvable cartridge embodiments, the bottle 100 may not have abulkhead 118 or doser 400. In dissolvable cartridge embodiments, theentire contents of the cartridge 200, 300 are mixed with the entirecontents of the bulk chamber 102.

In embodiments with replaceable, non-dissolvable cartridges, the topopening of the cartridges 200, 300 can be sealed in various ways toprevent leakage prior to use. In one embodiment, cartridges 200, 300 aresealed by a puncture seal, i.e., a seal designed to be readily puncturedwhich self-seals around the puncture, such as a rubber film. In anotherembodiment, a reusable rubber stopper is fitted to the top of thecartridges 200, 300 to provide a seal to prevent the additive liquid 122from leaking.

Referring to FIG. 2, the bottle 100 can be a reusable and refillablebottle 100 upon using up all the bulk liquid 120 or the additive liquid122. In one embodiment, the bulkhead 118 can be separated from the bulkchamber 102 to initially fill or to re-fill the bulk chamber 102 with ahair care product, for example. Then, the bulkhead 118 is reattached tothe bulk chamber 102. A cartridge 200 or 300 is selected and placed inthe opening 114 into the magazine 106.

Next, the cap 104 is reattached to the bulkhead 118, and in the processthe cartridge 200 is sealed to the additive liquid doser 400 housed inthe cap 104.

In one embodiment, the additive liquid doser 400 is for dosing theadditive liquid 122 from the cartridge 200. In one embodiment, theadditive liquid doser 400 is for dosing a small amount of additiveliquid 122 into the bulk liquid 120 that is being dosed. The additiveliquid 122 can be dosed in pre-determined quantities or in a varyingquantity. The additive liquid doser 400 therefore is configure fordosing an amount of additive liquid 122 less than the entire amount inthe cartridge 200, 300. Dosing can be a continuous infusion of theadditive liquid 122 in the stream of bulk liquid 120 with or withoutturbulent stream mixing. Dosing can be a single dose of additive liquid122 delivered to a mixing chamber of predetermined volume, following bymixing with the stream of bulk liquid 120. In order to withdraw theadditive liquid 122 from the cartridge 200, dose the additive liquid,and infuse the additive liquid 122 into the bulk liquid 120 severaltechniques can be employed.

Referring to FIG. 4A, in one embodiment, the additive liquid doser 400includes a mixer 410, such as a venturi mixer. In this embodiment,squeezing the bulk chamber 102 forces the bulk liquid 120 into and upthrough the diptube 108, whereafter the liquid 120 passes through thethroat of the venturi 410 thereby drawing the additive liquid 122 by theventuri effect, thereby also mixing the additive liquid 122 in thestream of bulk liquid 120. In FIG. 4A, a diptube 402 with a rubberstopper 406 for sealing the opening in the cartridge 200 is illustrated.A similar diptube and rubber stopper can be applied to all embodimentsof the additive liquid doser 400.

Referring to FIG. 4B, in one embodiment, the additive liquid doser 400includes a dosing chamber 420 having a predetermined volume. In thisembodiment, a first one-way valve 426 is provided at the top end of thediptube 422 for the additive liquid 122. A second one-way valve 424 isprovided at the top end of the diptube 108 for the bulk liquid 120.First and second one-way valves 426, 424 prevent liquids the return ofliquids from the dosing chamber 420 to the respective cartridge 200 andbulk chamber 102. In this embodiment, to dose the additive liquid 122 inthe dosing chamber 420 first, the bottom 100 is inverted to let theadditive liquid 122 drain by gravity into the chamber 420. Then, thebottle 100 is inverted again to end the dosing. The consumer may thensqueeze the bulk chamber 102 to force the bulk liquid 120 into thedosing chamber 420 where it may mix with the additive liquid 122 beforebeing expelled out from the dosing chamber 420 to the spout 116. Inanother embodiment, the bottle 100 does not need to be inverted to dosethe additive liquid 122 to the dosing chamber 420. Instead, the magazine106 and cartridge are made from a more pliable plastic than the bulkchamber 102. Therefore, upon squeezing the bulk chamber 102, thepressure is relieved by deforming the magazine 106 and cartridge 200first, followed by forcing the bulk liquid 120 up through the diptube108. In one embodiment, the main chamber 102 is squeezed to fill thedosing chamber 402 with the bulk liquid. Then, the bottle 100 can beinverted to allow a predetermined amount of additive liquid 122 into thedosing chamber 402. Shaking the bottle 100 can mix the additive liquid122 and the bulk liquid 120 to add color. Then, the levered spout 116can be opened, and the combined mixture can be poured out through thespout 116.

In one embodiment, the dosing chamber 420 and valves 424, 426 can beomitted. In this embodiment, the diptubes 422, 418 for the additiveliquid 122 and bulk liquid 120, respectively, are connected directly tothe outlet in the spout 116. Therefore, upon squeezing the bulk chamber102, the dispensing of the additive liquid 122 precedes, the dispensingof the bulk liquid 120. Thus, there is little to no mixing prior todispensing, and the customer may simply mix the liquids in the hand, orupon applying the liquids on the hair to work up to a lather.

Referring to FIG. 4C, in one embodiment, the additive liquid doser 400includes a pump assembly 412 to dose the additive liquid 122 into adosing chamber 408. For example, the pump assembly 412 includes a piston416 which can be directly linked to the levered spout 116, so that whenthe levered spout 116 is pushed down to open the dispensing passageway,a dose of the additive liquid 122 is delivered into the dosing chamber408. A one-way valve 440 prevents the additive liquid 122 from flowinginto the diptube 108 of the bulk liquid 120. In the pump assembly 412,the additive liquid 122 flows through the hollow center of the piston416 and then into a flexible tube 418 leading to the dosing chamber 408.The dosing of the additive liquid 122 becomes semi-automatic, becausethe levered spout 116 needs to be pressed down in order to dispense thebulk liquid 120. Thereafter, the consumer may then squeeze the bulkchamber 102 to force the bulk liquid 120 into the dosing chamber 408where it may mix with the additive liquid 122 before being expelled outfrom the dosing chamber 420 to the spout 116.

Referring to FIG. 4D, this embodiment of the additive liquid doser 400is similar to the embodiment of FIG. 4B, however, where one-way valvesare used in FIG. 4B, in FIG. 4D, a type of plug valve is used thatrequires manual assisted to open and close. The valve 434 on the diptube428 of the additive liquid 122 and the valve 432 on the diptube 108 ofthe bulk liquid are linked so that as one valve is opened the othervalve is closed. An indicator 436 can show which valve is presentlyopen. In this embodiment, the consumer may open the valve 434, closingthe valve 432, first to dose the additive liquid 122 into the dosingchamber 430 by squeezing the bulk chamber 102. Then, open the valve 432,closing the valve 434, to dispense the bulk liquid 120 to the dosingchamber 430 and then out of the spout 116 by further squeezing of thebulk chamber 102.

One embodiment of this disclosure relates to a dual chamber bottle witha doser for mixing and dispensing at least two liquids. The bottle holdsa first bulk liquid in a bulk chamber, and the bottle holds a secondadditive liquid in a cartridge. The first and second liquid aresegregated from each other. The doser is provided to dose the additiveliquid into the bulk liquid. The second liquid is an additive thatenhances a quality of the first liquid.
